如何检查Chrome中系统的时间格式-使用JavaScript是12个小时还是24个小时？

Question

date.toLocaleTimeString does not work in chrome and always return time in 12 hours format. I need to display time on the basis of system's time format.

Answer 1

Use

var x = date() 

// Tue May 15 2012 05:45:40 GMT-0500

They already provide you the datetime with the timezone

Answer 2

Short answer is No you can't get the default time format in the browser, because it relies on the System and on the browser settings, thought JavaScript doesn't have access for such options.

But if you want to manage the time format within your code, you can specify the format by which you wnat to show your Date.

Actually the toLocaleString() have a boolean hour12 option that tells the engine to use or not the 12 hours format:

console.log(date.toLocaleString('en-US', { hour12: false }));

If you set it to false it will display the time in 24 hours format.
